The Toughpower SFX 600W 80 Plus Gold Modular Power Supply from Thermaltake is a small and efficient SFX power supply designed with a single +12V rail for stability and compatibility among current generation hardware. It's built with multiple heavy-duty protection features and its modular design allows you to connect only the cables you need. Unused cables can be stored should you decide to upgrade your system down the road. With less cable clutter, there will be better airflow within the chassis for lower temperatures. Furthermore, it comes with an SFX to ATX adapter bracket so it can be used with any case. A built-in 80mm fan operates silently and provides additional heat dissipation.
